PHYS 1500 Lecture Notes - Lecture 22: Perfect Fluid, Surface Tension
Document Summary
If fluid is flowing through pipe, same amount of fluid will travel the entire time regardless of changes in pipe. Speed is high where the pipe is narrow and speed is low where the pipe has a large diameter. It is a consequence of conservation of energy is applied to ideal fluid. It assumes the fluid is incompressible and nonviscous, and flows in a nonturbulent, steady-state manner. ^it shows fluid flowing through a horizontal constricted pipe. Speed changes as diameter changes and can be used to measure the speed of the fluid flow. Swiftly moving fluids exert less pressure than do slowly moving fluids. The air speed above the wing is greater than the speed below. The air pressure above the wing is less than the air pressure below. ^^that causes a net upward force called a lift. The net effect of this pull on all the surface molecules is to make the surface of the liquid contract.
